This language typically gives the impression that having a control enhances credibility. But what exactly does “control” mean? And should you be impressed by it? I’ve been a statistician for many years, and my recent research has shown that 90% of American adults would base decisions on statistics, at least sometimes, if they understood the basic concepts better. Control is one such concept. Understanding controls can help you assess how well a study’s conclusions are supported by evidence, and can help you judge the media’s interpretation of new research.
